Re: Smarter Sort

[Søren Hauberg]

Hi,
I haven't thought this through so there's a pretty good chance all I'm 
saying is nonsense, but here goes...
I'd start out by creating a vector containing the numbers you want to 
sort by, i.e. (assuming your cell array is called C)

for i = 1:length(C)
        A(i) = str2num(C({i}); # This is not good enough
endfor

then call sort with an extra output argument:

[XXX, idx] = sort(A);

And finally sort your cell array using idx,

C = C{idx};

Don't know if it works, but it might get you started,
